y. improved finding apparatus embodies a switch'B of a slab 1 lating 'material and formed with a rearwardly projecting marginal flange 2. Secured to the rear face of the slab 1 adjacent to the upper end thereof is a segmental contactstrip 3 and disposed below the strip 3 concentrically of the center of the arc of distances and fastened to the back face of the slab in some suitable manner. Formed in the slab concentrically of'the circle de- Fig. 4 is a longitudinal view on the line 55 of' brush or roller therewhile the remainin terj vibrator coils b hav of a two-way switch c,

comprising a body in the form preferably composed of insuspaced apart equal scribed by 'the strip 3 and contacts 4 is an opening 5 and rotatably mounted within the opening 5 is a receptacle 6 preferably composed of insulating material and having the 5 inner end thereof closed and formed with a peripheral flange 7 engaging in a circular groove 8 formed in the rear face of the slab -1 contiguous to the inner end of the opening 5. Secured to the rear end of the receptacle 10 ,6 at diametrically opposite points are sectorlike strips 8' formed, respectively with out.- wardly projecting fingers 9, 10 diametrically opposed and adapted to engage the segmental strip 3 and the contacts 4 respectively, the finger 10 being movable into engagement with any one of the contacts 4,"

while the finger 9 rides upon the strip 3. The end wall of the receptacle 7 is'equipped with a contactll and disposed Within the receptacle is a threaded shell 12 and the a contact 11 and shell 12 are connected by way of wires 13 with the respective sector-like strips 8 and threaded into the shell 12 is the butt of a signal lamp 14, the terminalsof the lamp'let being electrically connected with the contact 11 and shell 12 respectively. The front end of therece-ptacle 6 projects beyond the front face of the slab '1 and surrounding the projecting end of the 80 receptacle and suitably fixed thereto is a collar 15 formed with a radially projecting indicating finger 16 by means of which the receptacle may be revolved within the opening 5 to move the finger 10 into engagement with any one of the contacts 1. The outer face of the slab 1 concentrically of the circular path ofthe finger 16 is provided with indicating marks 17 corresponding in number with the contacts at and indicative of the positions of the respective contacts so that by moving the finger 16 into registration with one of the marks 17 the finger 10 will be engaged with the corresponding contact 4:, thereby electrically connecting the segmental strip 3 and the particular contact 4 by way of the finger 9, strip 8, lamp filament, the remaining strip 8 and the finger .10, the lamp filament being connected in series with the bridged segmental strip and contact. Formed in the slab 1 adjacent to the lower end thereof and spaced apart across the slab are openings 18 corresponding .in number with the contacts 4' and slidably mounted within the respective openings 18 are plungers19 having the inner ends" thereof equipped with heads 20 seating in recesses 21 formed in the back face of the slab contiguous to the inner ends of,-

the respective openings 18. Fastened to die 50 rear face offthejslab below the openings I 18 is, a ground plate 22 and formed on the ground plate 22 and projecting upwardly therefrom are spring contact fingers 23.having the upper ends thereof terminating at the rear of the plungers 19* respectivelyau f -in engagement with the heads 20 of such offset and spaced apart from the confronting portions of the respective fingers 23. Thus, the fingers 23 are normally out of engagement with the contacts 21 and when .c any. one of the plungers 19 is pressed inwardly against the resistance of the spring finger 23, the latter is actuated into engage ment with the companion contact 21. The contacts 21 are connected, respectively, with the contacts 4 by way of fusible wires In the present instance, the rear edge of the flange 2'at opposite pointsis formed with recesses 26 and these recesses 26 are adapted to receive lugs 27 formed upon the opposite edges of a closure plate 28. The plate 28 is movable into the space between the walls of the flange 2 and when in this position the lugs-27 engage in the recesses 26 and are held therein by means of suitable binding screws that are passed through openings in the lugs and into the adjacent portion of the flange 2. The inner face of this closure plate 28 is preferably formed with grooves 29 designed 'toireceive thevarious contacts, contact fingers, etc., on the rear face of the slab 1 so that the elements on the rear face of the slab will be segregated from each other in order to avoid short circuiting and the like.

In accordance with my present invention,

brator coils respectively, that is, to say, the

terminals of the primary windings of the vibrator coils connected with the stationary contacts respectively of the timer, and the segmental contact strip 3 of the switch is connected by way of a conductor 31 with the blade of the switch 6, while the plate 22 is grounded upon the engine as at 32 to correspond with the grounded side of the battery (I of the ignition system. By means of this construction and arrangement, it will be seen that when the switch e is on the battery connection and the receptacle 6 rotated to engage the contact finger 10 with the'contacts 1 successively, the filament of the lamp 14 will be energized when the driver of thevehillwill be advised of. the

cylinder in which "is e plug connected with the timer is located Fe the roller of the time i I nected with the a?:,,- and inei rt' it st a ih hesiaa H a i winding r instance, should I 8, the contact finger the timer and back to the battery,

* between two adjacent contacts the lamp lt'willremain denergize'd in the vibrator coil connected with suchtimercontact, and the switch 6 closed, current will flow from one" side of the battery 03 through the switch 6, conductor31, contact strip 3,

contact finger 9, contactstrip 8, the filament of the lamp 141-, the remaining contact strip 10, the particular contact i engagedby such, finger, the wire 30, the connection between the wi're '30 and said timer contact, the brush or roller of illustratedin'Fig. l of the drawings Thus, the lamp will be energiz'ed and the operator notified thatthe spark plugs is connected with the roller of the timer. A primary chargemay now b'e'injected into this cylinder under pressure.

Should the contactroller be in a, position of the timer,

. movement of the contact'fin'ger 10 overthe contacts 4.

However, the operator may 'energize any one of the spark plugs by pushing the corresponding plunger 19, or all of the plugs maybe energized simultaneou'sly by depressing all of the plungers. For instance, should the operator-depress the plunger corresponding to the plug a and the blade of the switch 0 be on the battery contact current will flow from one side of thebattery at through the primary winding ofthe coil corresponding-to the plug a the conductor 30, the contact 24 connected tothe eonductor' 30, the-contact finger 23, ground plate 22, ground 32, and back to the other side of the battery: by way of the grounded terminal thereof. Thus, a current will be induced in the secondary winding of the coil connected withthe plug (f, such current flowing from one side of the secondary winding of such c011, through the plug cf, the ground, through the timer 0 located upon the dashboard of the vehicle within the vision of the operator and havand back to the'other side of the secondary winding through the connection between the timer and the primary winding of the coil connected with the plug a In the present embodiment of my invention, I have shownthe spark plug finding apparatus as used in con unction w1th a starting mechanism comprising a tank 33 ing the upper end thereof provided with a filling opening 34 and the front wall thereof equipped :with a gageglass whereby the quantity of gasolene in the tank may be at all times determined. Disposed within convenient reach of the driver of the vehicle is an appropriate form of pump 36 and connected with the outlet of the pump 36 ,is 'a tube 37 connected with one end of a pipe 38 and the remaining end of, the pipe 38 is connected with a. manifold 39. Lead-= ing from the outlet of the tank 33 is a pipe 40 provided with a cut-off cook 41, and this as clearly.

pipes-.0 is tapped into the pipe 38. Leading from the manifold 39 are tubes 4C2 corresponding in number with the cylinders of the engine and connected with such cylinders respectively and each tube 42 is provided with a cut-off cook 43. ,If desired,

the ends of the tubesleading into. the repriming spark plugs 414:.- In' practice, previous to the energization of the spark plug in'the particular cylinder, the cook 43 in the tube 42 connected with such cylinder is opened and the cook 41 opened to permit a quantity of gasolene to flow into the pipe 38 and then closed. The pump 36 is now operated and forces the gasolene and air through the pipe 38, manifold 39, the open 'spective cylinders may be connected with T valve 43 and the tube 42 into the cylinder and the gasolene and air enter the cylinder in the'form of a combustible mixture so that when the spark is produced in the cylinder, this mixture which is under pressure, due to thepump 36, is exploded. Each tube 42 is preferably equlpped with a check valve 45 adjacent to the particular cylinder so as to prevent back flow of the mixture into the tube.

From the foregoing description taken in connection with the accompanying draw-' ings, the construction, mode of operation and mannerof employing my invention will be readily apparent. It will be seen that I have provided apparatus whereby the spark plug connected with the roller of the timer may be located or found and then energized to explode a priming charge inthe particular cylinder so that the engine may be started and enabled to pick up its own cycle of operation; and whereby a spark may be. produced'in any or all of the cylinders independently of vthe timer so that priming charges in the cylinders maybe exploded irrespective of the position of the timer brush or roller with respect to the contacts.

If desired, all of .the cooks 43 maybe opened so that a priming charge will be delivered to each cylinder of the engine.

While I have herein shown and described a switch element movable oversaid contacts and connected with the spark coil side of the battery of the ignition system, and a signal connected in circuit with said element and adapted to be energized when the element engages the contact in circuit with the roller on the timer. l
